Darn thing fits in your pocket and weighs nothing!
Yup...and if you're going for just a 3 day hike or something of the sort you can carry all the fuel you need in a very small container. I find the whole lightweight hiking strategy stuff interesting...the concept seems sound assuming the hiker has the skill to deal with emergencies.
I mentioned Ray Jardine in my previous post...I read his book and he had some interesting calculations about the amount of weight you end up moving given a normal hiking day wearing standard hiking boots vs the weight of lightweight shoes. But to reduce the need for the heavy boots he advocates reducing the total pack weight to between roughly 10 pounds and 15 pounds or so (rough from memory numbers there). With the vastly lighter load and less weight in shoes the hiker can travel vastly more distance. He and his wife have done the Pacific coast trail 3 times that I'm aware of...the first with the standard heavy pack method and 2 without.
